On the Performance of DVB-T2 MISO System: Special Fixed Transmission Scenarios

The Second Generation Digital Video Broadcasting Terrestrial (DVB-T2) system has the most complex and flexible configuration among the second generation DVB standards. It also supports the multiple-input single-output (MISO) transmit diversity to improve terrestrial TV broadcasting in the Single Frequency Networks (SFNs). This paper deals with the performance study of DVB-T2 using MISO at special fixed transmission scenarios. These scenarios are characterized by different channel conditions between the transmitters (TXs) and receiver (RX) and different power imbalances between TXs. A laboratory workplace enabling to measure the DVB-T2 MISO signal on both objective and subjective levels is realized. Results show that the considered transmission conditions have different influence on the overall performance of MISO-based DVB-T2 system.
